Ikaros

Introduced as a "Pet-Class Angeloid, Type Alpha", she becomes bonded to Tomoki at the beginning of the story (symbolized by the invisible chain leading from her collar to Tomoki's hand). Ikaros displays a very submissive, melancholic personality, and is completely subservient to Tomoki's wishes. Ikaros possesses the ability to grant seemingly any wish through the use of several techno-magical cards. Despite her passive appearance, Ikaros has displayed moments of aggressiveness when Tomoki's life appears to be in danger. She weighs 48 kilograms, stands at 162cm and her wing type is listed as "Variable". Her "Variable" wings are extremely valuable and are highly desired by Synapse. While she begins the series with a poor grasp of human emotion, she eventually begins to acquire emotions and begins to fall in love with Tomoki. The reason for this is because she has high battle and processing capability, but low emotional control. She has been shown to be willing to sacrifice herself if it means ensuring the safety of Tomoki. Recently, her feelings for Tomoki have grown even further, evidenced by the fact that she blushed and felt embarrassed when she accidentally saw Tomoki's kissing face.

As the story progresses it becomes clear that Ikaros is not merely a "Pet-Class" Angeloid, she is actually a "Battle-Class" Angeloid and also the most powerful of all Angeloids. She takes little harm when she is shot, she is capable of flight at Mach 24, and is able to withstand pressure better than most submarines. In the past, she was called the "Uranus Queen" and terrorized Synapse due to her immense power and battle capabilities. She was originally sent to Earth as a weapon of judgment and is responsible for destroying the tower of Babel.

Ikaros is seen to be with the only Angeloid who has a 'battle mode'. When she activates her battle mode (Uranos Queen Mode), her wings are engulfed in bright light, and her eyes become red and a halo appears over her head. Ikaros can generate a nigh-invincible energy shield called 'Aegis' named after the shield used by Zeus the chief Greek god. She also possesses two powerful weapon systems; 'Artemis' named after the Greek goddess of the moon and hunting, a series of multi-directional, homing energy projectiles fired from her wings, and 'Apollon' named after the Greek god Apollo of light, medicine and other various things, a bow that can fire energy-charged arrows capable of obliterating a country in a single shot. Both of her weapons' names are associated with Greek gods whose weapon of choice is the bow and arrow. She possesses a third weapon called 'Hephaestus', named after the Greek god of fire and blacksmith. It may be powerful enough to blow up a mountain when asked by Mikako Satsukitane when she wanted to dig up a hot spring. It was first seen when used in battle against the twin Gamma Harpies. It is an intensely powerful cannon that dwarfs Gamma's Prometheus in firepower and size. A running gag involves Ikaros occasionally seen holding a watermelon, a fruit she curiously takes an interest in. In the manga, this leads her to eventually grow a patch of watermelons in the garden.
